    mirella8.ru if you did this site, then you do not need to do more WEB. I waited a long time for it to load, then set the desired encoding, it is different on all pages. Engage in system programming in Delphi. Web - no need :) - Artem

I looked at the functions imported from WINMM.DLL in one volume control, here is their list:

 mixerGetLineInfo mixerGetDevCaps mixerGetNumDevs mixerGetControlDetails mixerSetControlDetails mixerOpen mixerGetLineControls mixerClose

The prefix mixer tells us (at least to me) that they are somehow related to volume control. In the rest, Google to help.

PS here, google sample code: "How to work with a mixer?"

    What are you fucking Michael? Is it not clear that he wants to learn how to adjust the volume of the computer, and not control signals like beep. There seems to be some kind of API function. I also wanted to read the answers on this issue.
